fr = 7.5*((fck)^(1/2))
This formula uses 2 Variables
Variables Used
Modulus of Rupture of Concrete - (Measured in Pascal) - Modulus of Rupture of Concrete is a measure of the tensile strength of concrete beams or slabs.
Characteristic Compressive Strength - (Measured in Pascal) - The characteristic compressive strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.
STEP 1: Convert Input(s) to Base Unit
Characteristic Compressive Strength: 20 Megapascal --> 20000000 Pascal (Check conversion ​here)
STEP 2: Evaluate Formula
